Abstract (en)
[origin: WO2016068945A1] Printheads and methods for forming printheads are described herein. In one example, a printhead includes a single resistor window in a conducting layer within the printhead. The printhead also includes a number of resistors formed in a resistor film deposited over the single resistor window. The resistors have two different widths, and each of the two different widths ejects a different droplet size when energized.
